I've had a WordPress account for quite some time. I'm currently using Tumblr to blog. I'm wondering, what...if any advantage there is to having more than one blog? Is it just redundant to be posting similar content in two different places? Do I, by posting content in two different spaces, open things up to a wider audience? Especially if I am pushing all of it to platforms like Twitter? I'm sure others have had these questions before...that's why I am asking now...to "lean" on the experience of others before me. Thoughts?
